UltraLok 330 is a two-part methacrylate, structural bonding adhesive designed for the structural bonding of various substrates, including fiberglass, steel, aluminum, and various plastics (not low energy surfaces). Combined at a ratio of 1:1, UltraLok® has a working time of 18 to 25 minutes and achieves nearly 90 percent of its ultimate strength in 30 to 50 minutes at room temperature curing. UltraLok® provides high strength bonds to the above reference surfaces with generally no preparation effort. UltraLok® bonds very strongly to steel, stainless steel, and aluminum metals. UltraLok® adhesives are NOT UV STABLE, AND WILL YELLOW OVER TIME This yellowing will not affect bond performance, but will affect bond appearance.
